When Estee Lauder conquered the world with a small brown bottle, Lancôme also launched a small black bottle with the core ingredient of bifida yeast fermentation product lysate with the concept of skin essence, which was recognized by users. When the Iron Man mask containing the essence of the small brown bottle was selling well, Lancôme was naturally not to be outdone by launching the small black bottle mask, as a "first-aid" product, which is a supplement to the daily maintenance of the small black bottle.
 
Officially, a small black bottle mask is equivalent to a bottle of small black bottle essence, which is true in terms of capacity, but the formula of the two is not exactly the same. Of course, bifida yeast fermentation product lysate is still the core ingredient of the small black bottle mask, which has nothing to do with yeast, but is actually a composite product obtained by bifidobacteria culture, inactivation and decomposition. The substance is claimed to speed up skin renewal and leave skin looking supple and smooth. In addition, the mask removes alcohol and adds a pH adjuster to reduce skin irritation. At the same time, moisturizers and anti-inflammatory soothing ingredients are added, which are more moisturizing than the little black bottle, and also have a certain relieving effect on sudden acne and other problems, which is suitable for emergency role.
 
The effect of the small black bottle mask is quite recognized by users, but the use experience is not very comfortable. The mask is not well cut and does not match the shape of the face exactly, for example, the eye distance is too wide, and the inner corner of the eye of some users is easy to touch the mask cloth. The mask cloth is also not conformable, bubbles and wrinkles often appear, and if you don't use it on your back, the mask will be slippery. In addition, the smell of the mask is too strong. Compared with the price of a single piece of nearly 100, the use of the small black bottle mask does have a lot of room for improvement.
